A teenage singer whose debut single was a tribute to her dying mother recorded on a mobile phone has gone into the studio to record a follow-up.

Sarah Phillips, from Chiswick, west London, was only 16 when she recorded the poignant version of Paolo Nutini's Autumn on the evening her mother, Debbie, died.

She sang the song alone in her bedroom, recording it on her phone, and it was played at Mrs Phillips' funeral and uploaded to YouTube, where it became an internet sensation.

It received more than 200,000 hits within days and eventually reached the Top 10 on the iTunes chart and number 49 in the Official UK Chart, raising £350,000 for a cervical cancer research fund set up in memory of her mother.

Sarah, now 17, went into the studio this week to record Blue Chair which she she co-wrote with a family friend, songwriter Charlie Mole.

Sarah said: "Having raised awareness and money for the fund, Blue Chair is a positive and uplifting follow up to Autumn. I hope that we can release it as a charity single later in the year and raise more money."
